Does lacquer go bad?

Does lacquer go bad?

---

I have a few unopened quarts of Deft lacquer that have been sitting in my shop for the last 5 years. Any chance that this stuff is still usable?

Thoughts of Chairman Al:

It depends what type of lacquer. If we are talking about cellulose, pre cat or two pack lacquers I would advise differently.

1. As ‘neat’ cellulose is a ‘pure’ product I would say as long as the can is firmly sealed and kept in a cool place this should be o.k. 
2. As pre cat is a mixture of catylizing agent and cellulose, I would say don’t use after year.
3. As a two pack, the lacquer and catalyzing are seperate.  It will last longer, but, as to lasting five years, I wouldn’t use it!
